At home on the road? Can drivers' relationships with their cars be associated with territoriality?

The current research explores the relationship between people and their cars within the framework of Altman's theory of human territoriality. It further develops the research of Sandqvist by examining the descriptions given by people with differing ownership and uses of their cars and exploring the congruence between these and the characteristics used to describe human territories. Thirteen focus groups were held with young drivers between the ages of 18 and 25 years, drivers over the age of 25 who are parents of pre-license age children, drivers over the age of 25 who do not regularly transport children, and drivers of work vehicles. Analyses of discussions revealed that drivers’ descriptions of the relationship with their car could be matched with Brown and Altman's descriptions of territory types. However, variations existed both between and within individuals as to the application of the labels ‘primary’, ‘secondary’ and ‘public’ territory to the car. Implications for the understanding of road user behaviour and the further development of theory on the car as a place or an object in terms of territoriality are discussed.

Why do people buy hybrid cars?

This article reports on the underlying dimensions used by petrol-electric hybrid and conventional car buyers when evaluating a vehicle with the intent to purchase. Buyers of conventionally fuelled vehicles reported that they considered quality and performance as the most important determinants of choice. They rated as least important, the image they derive from driving a particular car and social influence. On the other hand, petrol-electric hybrid car buyers reported that social influence and projecting a “green” image were most important considerations and quality and appeal were least important. These findings provide social marketers with a crucial understanding that helps in the selection of an appropriate model to promote the diffusion of eco-friendly vehicles.

A cloud of smug over outdoor education : South Park, hybrid cars and environmental morality

In an episode of South Park titled ‘Hey, People, You’ve Gotta Drive Hybrids Already’, Stan convinces townsfolk to buy hybrid cars. This reduces the rate of smog but creates a toxic cloud of ‘smug’. In this paper, I use this parody of eco-correctness to interrogate some of Outdoor Education’s environmental aims. Michel Foucault’s later work on the self, morality and governmentality is used to analyse the production of the [neo- iberal] ‘environmentally responsible citizen’. The possibilities and problems of contemporary citizenship discourse are explored in relation to findings from a longitudinal study of students undertaking a tertiary outdoor and environmental education course.

Buses, cars, bicycles and walkers the influence of the type of human transport on the flight responses of waterbirds

One way to manage disturbance to waterbirds in natural areas where humans require access is to promote the occurrence of stimuli for which birds tolerate closer approaches, and so cause fewer responses. We conducted 730 experimental approaches to 39 species of waterbird, using five stimulus types (single walker, three walkers, bicycle, car and bus) selected to mimic different human management options available for a controlled access, Ramsar-listed wetland. Across species, where differences existed (56% of 25 cases), motor vehicles always evoked shorter flight-initiation distances (FID) than humans on foot. The influence of stimulus type on FID varied across four species for which enough data were available for complete cross-stimulus analysis. All four varied FID in relation to stimuli, differing in 4 to 7 of 10 possible comparisons. Where differences occurred, the effect size was generally modest, suggesting that managing stimulus type (e.g. by requiring people to use vehicles) may have species-specific, modest benefits, at least for the waterbirds we studied. However, different stimulus types have different capacities to reduce the frequency of disturbance (i.e. by carrying more people) and vary in their capacity to travel around important habitat

Are vehicles 'mobile bird hides'?: A test of the hypothesis that 'cars cause less disturbance'

We tested the 'cars cause less disturbance' hypothesis by comparing the flight-initiation distance (FID) evoked by a car versus a single walker for 38 species of waterbird (n = 657 standardised approaches). For the 15 species where we had sample size adequate for statistical testing (n ≥ 5), we found that cars elicited shorter responses after controlling for starting distance. Within-species analyses revealed that this difference was significant in 8 of 15 species. Although mean FIDs for car approaches were always shorter than FIDs toward single walkers in the remaining species (7), the tests in those species lacked sufficient power to draw meaningful conclusions. Our results provide support for the hypothesis that birds respond to cars at shorter distances. The wide taxonomic breadth of species investigated suggests that this principle may be broadly applicable, at least in waterbirds. The results of this study and the FID estimates we present will allow development of meaningful stimulus-specific buffer zones to protect waterbirds from disturbance.

Psychological and situational influences on commuter-transport-mode choice

The relative importance and relationship between psychological and situational factors in predicting commuter-transport-mode choice was tested by four hypotheses. First, the influence of individuals’ values on commuter behavior is mediated by their corresponding beliefs about the environmental threat of cars (mediation hypothesis). Second, the influence of these beliefs on behavior is moderated by individual consideration of future consequences and control beliefs (moderation hypothesis). Third, cost, time, and access factors contribute to individuals’ commuter choice (situational hypothesis). Fourth, situational and psychological factors jointly influence proenvironmental behavior (interaction hypothesis). A sample of 205 Australian university students completed a survey to measure these relationships. Regression analyses indicated support for the mediation, situational, and interaction hypotheses. It was concluded that to achieve a transport-mode shift to public transport, public policy strategies should focus on individuals’ transport-related environmental beliefs (personal control and environmental effect of cars) and situations (access to public transport at reduced cost).

Speed control and policing in a cellular mobile network: speedNet

In this paper, we describe SpeedNet, a GSM network variant which resembles an ad hoc wireless mobile network where base stations keep track of the velocities of mobile users (cars). SpeedNet is intended to track mobile users and their speed passively for both speed policing and control of traffic. The speed of the vehicle is controlled in a speed critical zone by means of an electro-mechanical control system, suitably referred to as VVLS (Vehicular Velocity Limiting System). VVLS is mounted on the vehicle and responds to the command signals generated by the base station. It also determines the next base station to handoff, in order to improve the connection reliability and bandwidth efficiency of the underlying network. Robust Extended Kalman Filter (REKF) is used as a passive velocity estimator of the mobile user with the widely used proportional and integral controller speed control. We demonstrate through simulation and analysis that our prediction algorithm can successfully estimate the mobile user’s velocity with low system complexity as it requires two closest mobile base station measurements and also it is robust against system uncertainties due to the inherent deterministic nature in the mobility model.

Childhood obesity - a sign of commercial success, but a market failure.

'Obesogenic' products, such as energy dense foods, passive entertainment products, cars, and labour-saving devices, are widely available and heavily promoted. Because they are highly consumed and very profitable, obesity becomes the inevitable consequence of their commercial successes. Contemporary market forces heavily favour behaviours for short-term preferences (i.e. over-consumption and underactivity) over long-term preferences (i.e. healthy weight) and this is especially true for children. Hence, if the market, as the main mechanism for determining choices, results in outcomes, which make our children worse off, as is occurring with childhood obesity, then the market has failed to sustain and promote social and individual goals. This is a serious market failure. In the current obesogenic environment, expecting adults, let alone children, to make food and activity choices in their own best long-term interests is, therefore, demonstrably flawed. We argue that significant government intervention is needed to correct this market failure, as has been done for other major health problems.

Consumer responses to free service trial offers

Consumers find it difficult to evaluate services they have not previously used, especially where these services have high experience or credence properties (Mittal 2002, 2004). A frequent promotional strategy used by marketers is to offer a free trial, such as a free brake check on cars or a free session at a new gym. While there is extensive literature on product trials, very little research has been conducted on free service trial offers. This led the researchers to undertake preliminary content analysis and qualitative interviews and ultimately to develop a comprehensive model of consumer evaluations of these offers. The model takes account of the type of service on offer, the manner in which it is offered and the pricing mechanism used (free versus discounted). It also characterizes the cognitive and emotional evaluations consumers make in response to these offers and how these contribute to trial and purchase propensity. Individual characteristics of consumers, such as deal proneness, were also incorporated into the model. The current study reports an experiment where the model was systematically tested among groups of male and female consumers (in total 400) who varied by age group and service experience. The research indicated that a free trial offer operated rather differently from a discount, inducing a sense of obligation which motivated some people to adopt the trial and subsequent full service offer. Traditional trial-cognition-evaluation models (e.g. Smith and Swinyard, 1983) are not sufficient to explain the phenomena uncovered by this research.
